<p>PROBLEM TO BE SOLVED: To provide a liquid discharge head which achieves improvement of adhesion between an organic liquid repellent film and a nozzle base material and improvement of liquid resistance.SOLUTION: In a nozzle plate 102, a surface treatment film 120 is formed on a surface of a nozzle base material 110 and an organic liquid repellent film 121 is formed on the surface treatment film 120. The surface treatment film 120 is an oxide film including Si. The oxide film includes a transition metal which forms a passive film, such as aluminum, bismuth, antimony, tantalum, niobium, titanium, hafnium, and tungsten.</p> |
